Overview

The Yokogawa SNB10D-225/CU2T is a high-reliability rack control module designed for use in ProSafe-RS safety systems, which are widely deployed in industries such as oil & gas, petrochemicals, and power generation. This complete set includes the backplane node unit, control unit, and associated modules, offering a fully integrated solution for safety-critical automation.

Moreover, the SNB10D-225/CU2T supports dual redundancy, ensuring continuous operation even in the event of a hardware failure. It operates across a wide temperature range from –40°C to +100°C, making it suitable for extreme environments. Therefore, it is trusted in over 2,400 global safety projects where milliseconds matter for fault detection and response.

Key Specifications

Typical Applications

• Emergency Shutdown Systems (ESD) – Rapid fault detection and isolation in hazardous process environments.

• Fire and Gas Systems (F&G) – Interfaces with sensors and actuators for fire suppression and gas leak detection.

• High-Integrity Pressure Protection Systems (HIPPS) – Ensures safe operation of pipelines and pressure vessels.

• Distributed Safety Architectures – Supports modular and scalable safety control across large facilities.

• Offshore and Remote Installations – Operates reliably in extreme temperatures and vibration-prone environments.

The SNB10D-225/CU2T is often used in brownfield upgrades, replacing legacy safety systems with modern SIL3-certified solutions.
